OBJECTIVE To show the institutional experience of closure of interatrial communications with a modified umbrella device. DESIGN Descriptive study of all patients in whom transcatheter umbrella closure of interatrial communications has been attempted. SETTING A tertiary referral centre. PATIENTS 16 patients with 17 interatrial communications of various types. INTERVENTIONS Transcatheter ...

[1] Photographs of a volcanic column in a recent eruption of Reventador show a prominently scalloped umbrella that is unlike any umbrella previously documented on a volcanic column. We propose that the scallops in this umbrella are the result of a turbulent Rayleigh–Taylor (RT) instability, a type of fluid instability with no precedents in volcanology. Negative buoyancy drives this instability,...

The notion of umbrella contingencies is rigorously defined in the context of the security-constrained optimal power flow (SCOPF) problem in both its deterministic and probabilistic forms. The set of umbrella contingencies is a subset of the set of credible contingencies that is sufficient to attain levels of security and economic performance identical or nearly identical to those found when all...

This paper considers the problem of testing for umbrella alternatives in the one-way layout when survival data are subject to random right censorship. Testing procedures based on two-sample weighted logrank statistics are suggested for both cases when the peak of the umbrella is known or unknown. The Pitman efficacy of the peak-known umbrella test is derived. A class of Lehmann and scale altern...

Abstract A new methodology/data structure, the clause tree, is developed for automated reasoning based on resolution in first order logic. A clause tree T on a set S of clauses is a 4-tuple , where N is a set of nodes, divided into clause nodes and atom nodes, E is a set of edges, each of which joins a clause node to an atom node, L is a labeling of N ∪ E which assigns to each clause n...

By generalizing the notion of location of a constituent to allow discontinuous Ioctaions, one can describe the discontinuous constituents of non-configurational languages. These discontinuous constituents can be described by a variant of definite clause grammars, and these grammars can be used in conjunction with a proof procedure to create a parser for non-configurational languages.

The Clause slicing technique is a static slicing technique. The clause slice criterion is the clause, which is the smallest part of the code line, with the clause number. In this paper, we introduce the “Clauser,” which is a new clause slicing tool for C programs. The Clauser is a slicing tool that divides the program code lines into clauses, depending on certain rules, and then it slices the c...

0 Introduction This paper represents the continutation of research into the identiication of the relationship between the head of a relative clause and the clause body, for Japanese. Unlike many languages, a `trace' of the gap associated with the head of a gapping relative clause is not lexically marked in Japanese, and gapping and non-gapping clauses are not explicitly distinguished. Our curre...
